Does developing your psychic awareness have to be scary?

Could anyone please tell me what sort of things they have experienced when opening their third eye?... I hear whispers, scary voices and have a feeling of rushing dark shapes coming towards me when i meditate..verrrrry unnerving..so much so it's enough to make myself come out of it... For those of you who 'know' what i'm reffering to...Is this a temporay stage that will p? Could this be just in my mind, my imagination because i feel scared and unsafe.
